I love making dog treats, and this frozen watermelon dog treat recipe is one of my favorites. It's a great low calorie treat to help keep your dog cool in the summer, and since the only ingredient is the watermelon itself it's really easy to make. Chop some seedless watermelon into cubes, mix it in the blender until it's the consistency of a smoothie, freeze it for 3 hours and you're good to go. #dogtreats #dogs
